![]() This is an incentive for them to recycle.įor instance, Spa Monopole in Belgium already uses 50% rPET in their mineral water bottles. This is a virtuous circle: showing consumers that PET can be recycled back into a bottle. Currently, there’s not enough high-quality rPET available, but a number of major brands are still committed to using rPET. Brand owners are promoting even stronger specifications. Luc Desoutter: rPET can be used in PET bottles as long as it’s approved for food contact. What challenges are faced using these new polymers and where does Sidel see the future for rPET? Many brand owners are pushing for greater and greater proportions of recycled PET (rPET) in their bottles, while others are choosing to move over to plant-based PET. ![]() We achieved a reduction of 23% on neck finish weight and 13% on cap weight. Recently, Sidel worked on a short neck project for one of Danone’s bottled water brands.This ultra-lightweight is accomplished by the overstroke base technology. The PET bottle SmartWeight for still water offers high user comfort with less than 10g for a 50cl bottle.It can be manufactured and distributed on an industrial scale and weighs between 25% and 40% less than an average water bottle with the same capacity, resulting in less plastic material to be recycled. With only 9.9g per 50cl bottle, NoBottle was the first lightweight PET bottle below 10g.Over the past five years, Sidel has launched a number of innovative, lightweight bottles: The same bottle when treated with Actis Lite and reduced to 23g has a shelf life of over 20 weeks and results in an 18% saving of PET resin. For example, a 60cl PET carbonated drink bottle that weighs 25g has a shelf life of approximately eight weeks. When it comes to carbonated products, Sidel’s own Actis Lite technology accounts for significant savings in material costs due to a reduced bottle weight of 15% to 20%. Consumer acceptance, package quality perception and brand image can also define the limits. These can vary from one region to another. Luc Desoutter: Lightweighting can be further developed, but it has to be looked at in a holistic manner with secondary and tertiary packaging, taking into account all conveying, logistics and shelf life aspects. What’s next? Can bottles really become any lighter, and can production become even more energy efficient? How does Sidel see the future? In preform production and bottle blowing, huge energy savings have also been achieved. There have been dozens of lightweighting initiatives in the past few years, dramatically reducing wall thickness and neck heights.
